- e vide a turbine of the character described that is extremely rugged in'construction and in whichfpower is transmitted to a shaft running at right angles to the drive/shaft in a particularly efficient manner. Further'objects and advantages of my invention will appear as the specification proceeds. I v H The preferred form of my invention is illustrated in the accompanying drawing, in aowhich y Figure 1 shows a side elevation of my turbine; V

V .While I have shown only :the preferred form'of the invention, I wish to have it understood that various changes or modifications may be made within the scope of the claims. hereto attached without departing from the spirit of theinventionl The casing 1, which may be partly filled with oil, as indicated at 2, has a shaft 3 sup-v ported therein in journals 4i extending through the casing and supported in oppo-' site walls thereof. The shaft 3 has a worm 5 5:145 thereon, which meshes with a worm gear 6 on a transverse shaft 7 In adjacent relation to the housing 1,

there is provided a second housing 8 fastened 1 to the first housing by means of bolts 9, and

1* .50 one end of the shaft 8 extends into the second rings 27in the far end of the cylinder. i

housing and terminateswithin the same in a drum 10, which is revolvablymountedonja cylinder 11 extending into the second housing from the opposite side and incoaxial relation with the shaft 3, this cylinder havinga cap 12 for closing the same and being fastened to the housing by means ofbolts 13. The drum 10 is formed with two annular series of blades 14 and15arranged parallel to one another with the bladesinclined in opposite directions,as appears particularly well from a comparison of Figures 3 and 4. The

bladesare inclined in such a manner that a pressure medium active on the blades from the inside of the drum causes the drum to rotate in one direction or the other, according to which set or seriesof blades is used, The

cylinder 11 is formed with two parallel se-' ries of'perforations'l6 and 17, the two series registering with the two seriesiof blades re- 7 spectively, so that steam for whatever pressure medium is used may be j discharged through the perforations against the blades,

the amount ofsteam discharged depending upon the number'of perforations left uncovered,

For each set of perforations, there is provided a slidingvalve such as shown in perspective View in Figure 6, the two valves being shown in Figure 2 at 18 and 19 respecso tively. Each of these valves comprises a segment of a bar 20 curved to conform to the circumference of the cylinder 11 andformed i with a plurality ofteeth 21 in the inner face and two flat wings 22 extending from the sides for widening the outer bearing face, the

length of the wings coinciding with the space occupied by the perforationsl6 or 17, so that all the-perforations may 'be-covered at one time. The two segments 18 and 19 are actu-rii atedby two pinions 2 3 and Zirespectively, which latter are supported on longitudinal shafts 25 and 26 extending into the cylinder through the cover 12 and supported inbear- Each of the shafts '25 and 26 has a hand wheel'28v thereon. It will be noted thatby operation of either one of the hand wheels, one of the segments is operated and is made to cover-or uncover one or more ports 16 or '17; The outer-face of each segment, as far .as the latter extends beyond the wings 22, is

formed with transverse grooves 29 to allow free access of the steam or other pressure medium through the perfrations16 or 17 when the samearenot covered by the wings 22.

The segments are suitably guided in guide- 7 ways 31,82 and33."

I L Airing 34 is slidably mountedon the drum 10 "for coveringeither one. of theltwo sets of blades and is' actuated by a rod 35"slidably mounted inbearings, indicated at 36and 37, and operated by a handle 38-pivoted to the ithehousing 8 for guiding the ring 34, which latter is formed with cars 43, (seerFigure 3) i for accommodating the rods and '42. r
